A1227 Hall-Effect Latch

These Hall-effect latches are extremely temperature-stable and stress resistant sensor ICs especially suited for operation over extended temperature ranges to 150°C. Superior hightemperature performance is made possible through a novel Schmitt trigger circuit that maintains operate and release point.

A1227 Features

* ▪ Symmetrical switchpoints ▪ Superior temperature stability ▪ Operation from unregulated supply ▪ Open-drain 25 mA output ▪ Reverse battery protection ▪ Activate with small, commercially available permanent magnets ▪ Solid-state reliability ▪ Small size ▪ Resistant to physical stress ▪ Enhanced ESD
